Description

13W7MDN21W 627-83-8 Ethylene glycol distearate Glycol distearate Octadecanoic acid, 1,2-ethanediyl ester Glycol distearate [USAN] Ethylene distearate Stearic acid, ethylene ester (8CI) Octadecanoic acid, 1,1'-(1,2-ethanediyl) ester EINECS 211-014-3 Elfan L 310 Emerest 2355 1,2-Ethanediyl bis(octadecanoate) Ethylene glycol dioctadecanoate Ethylene glycol, distearate Ethylene stearate NSC 6820 Stearic acid, ethylene ester UNII-13W7MDN21W EC 211-014-3 (CAS 627-83-8) is a high-purity analytical reference standard with the molecular formula C38H74O4 and a molecular weight of 594.99 g/mol.

Based on its molecular formula C38H74O4, 13W7MDN21W 627-83-8 Ethylene glycol distearate Glycol distearate Octadecanoic acid, 1,2-ethanediyl ester Glycol distearate [USAN] Ethylene distearate Stearic acid, ethylene ester (8CI) Octadecanoic acid, 1,1'-(1,2-ethanediyl) ester EINECS 211-014-3 Elfan L 310 Emerest 2355 1,2-Ethanediyl bis(octadecanoate) Ethylene glycol dioctadecanoate Ethylene glycol, distearate Ethylene stearate NSC 6820 Stearic acid, ethylene ester UNII-13W7MDN21W EC 211-014-3 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 594.99 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
